Examples

>>> from pgmpy.factors.discrete import DiscreteFactor
>>> from pgmpy.factors import factor_product
>>> phi1 = DiscreteFactor(["x1", "x2", "x3"], [2, 3, 2], range(12))
>>> phi2 = DiscreteFactor(["x3", "x1"], [2, 2], range(1, 5))
>>> phi = factor_divide(phi1, phi2)
>>> phi.variables
['x1', 'x2', 'x3']
>>> phi.cardinality
array([2, 3, 2])
>>> phi.values
